Answer: B = 70°, b = 29.2; c = 29.2

Step-by-step explanation:

sum of angles in a triangle is 180

40+70 +X = 180

X is the last angle

110+x=180

x= 180-110 =70

A= 40°

B= 70°

C= 70°

the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C

2(x+4)/3 =12<br><br> What is da answearrrrrr
dem82 [27]

Answer:

x = 14

Step-by-step explanation:

Given

\frac{2(x+4)}{3} = 12

Multiply both sides by 3 to clear the fraction

2(x + 4) = 36 ( divide both sides by 2 )

x + 4 = 18 ( subtract 4 from both sides )

x = 14

7 being your answer.
